MacDonald, who is currently vice president of programming at A+E Networks UK, will assume the role later in 2013, which also includes the overseeing of Sky1+1 and Sky2.

"It is such an exciting time to be joining Sky1," MacDonald said.

"Sophie [Turner Laing - managing director of entertainment and news] has created a terrifically supportive and creative environment to work within and Stuart and his team of commissioners have been producing an exceptional slate of programs over the last few years.

"It will be an honor to be working with them and together taking Sky1 to even greater heights."

Murphy added: "I am delighted that Adam has accepted the role of director, Sky1.

"He's an ideal appointment - not only has he already run History to great success, but he shares our values of excellence and fun.

"We can't wait for him to join our fantastic commissioning and channel teams."

In his media career, MacDonald has previously held posts as controller of daytime and digital factual at ITV, head of daytime at Channel 4 and head of planning and scheduling and BBC One.

BBC executive Liam Keelan had previously been reported to have taken up the Sky1 director role, but he instead opted for the position of global editorial director BBC Worldwide.
